Abstract

Schizophyllum commune Fries is a member of the Hymeno­ mycetes. This genus has long intrigued mycologists because of the peculiar "spliit gills'' it characteristically possesses. For a long time, however, not much importance was attached to the fungus until it was reported from many parts or the world and its. pathogenicity as a wood-destroying agaric established. Despite these facts relatively little is known about the fungus. Perhaps the phase of development most completely described was the development of the "gills", Essig (1922). Because of the location of the hymenium and stipe attachment, Essig (1922) suggested that the fungus more properly belongs in the family Thellephoraceae rather than the Agaricaceae; however, further work in the develop­ment of the fungus, especially the cytology, must properly be accomplished before such a change can be made. The cytological work on Schizophyllum is very incomplete, especially the cytology of the basidia; and many stages of development involving work in this field have not been demonstrated. Problems are presented by the exceedingly small nuclei, the small basidia, the hardness of the sporophore, difficulty in staining, and the difficulty of sectioning the sporophore thin enough for cytological investigation.
